Anrl e m am my a it is especially designed for use on a linotype machine, it Will be evident that it canbe used in other places than on a linotype view of a a j stable machine.

7 Among he sali t objects of my inv ntion are; to royide a durable and univer- Sally adjustable bracke fo ed'ust bly holding'an elec c lamp o h lii i ane posit on pr vide a justable i t whic are capable of being securely locked in adjusted pQSitiQns; to provide a bracket in which a supporting member of tubular form, ha ing lect ic co d th rethrough, can be r i y e ached f m th brack y a late al move e t, u aking i pos ib to detach the lam and its cord from the bracket without t e necessity of pulling a c rd through a pipe r hole; and, n i nera to rovide an accuratel adjustable racket 151 j n wh h can e adjust quickly and securely locked in various positions.

said hand screw, 14,, is tightened, the body members, 3 and 3", are tightened upon the supporting rod, 1, and the lamp tube, 16, is clamped firmly withinth'e sleeve, 7, by the trated one practical embodiment of my'invention, I am aware that changes can be made therein without departing from the spirit thereof, and I do not limit the in vention to the showing other than by the claims herewith.

I claim:'

1. An adjustable bracketincluding a rod, f

a split member adjustably mounted thereon,

a sleeve having an interfitting connection at its end with one side of said split member, a holding member telescoping through said sleeve and said split member, a spring in said sleeve operating to normally force said holding member outwardly, said holdin member being slotted along its opposite sides and said sleevebeing slotted in its end,and a hand nut and screw means -for drawingsaid members together in clamping relationship, said holding member'and said sleeve being adapted to hold another memher in said slots.

Y 2. In a device of the character referred to, in combination, 'asleeve slotted fromone end inwardly on oppos te sldes, means for supportingthe same, a member telescoping into said sleeve'and having a slot therein from one end for apart of lts length, said means at the other "end of saidsleeve" and extending through said supporting means forpulling said memberinto'said sleeve, and a member inserted sldewise into the open ends of said slots in said sleeve 'and'telescoping member, said telesco 'aing member clamping saidflatter member in place at I the outerend of said'sleeve.

ill)

3.1m combination, a sleeve slotted from oneend inwardly on opposite sides, a tubular member telescoping through said sleeve, said tubular member having a slot longitudinally thereof for a part of its length from its outer end, the inner end of said slot he-l ingofiset to form in efiect an openingtransversely through said member opening into the .slot at opposite sides thereof, a member transversely through said sleeve and adapted to rest through the opening at the inner end of the slot and to rest in said offset opening, whereby when said sleeve is turned said member can be removed laterally through said slot, means" at the other' end of said sleeve, attached to said telescoping member, for drawing said telescoping memher into said sleeve for securing said mem- 'member telescoping throu her which extends through said sleeve transversely in clamped position.

4.'In an adjustable bracket, a support, a clampin member adjustable on said support, a sleeve interfitting at one end with the side of said clamping member, a slotted h said sleeve, a screw secured at one end to said slotted member within said sleeve and extending through said clamping member, a hand nut on said screw for drawing saidslotted member into said sleeve and for clamping said clamping member on said support, anda spring in said sleeve operating normally to force said slotted member outwardly as said hand nut is released, said slotted member being adapted to adjust-ably hold a tubular like member inserted therein transversely. 4 5. In a device of the character referred to, two telescoping tubular members having their outerends slotted from their ends inwardly on opposite sides, said slots being in register with each other, the slot in the inner member turning in opposite directions at their inner ends, means for drawing the inner member inwardly, neanssupporting said members with their slotted ends free to receive transversely amemher to be held,

and a member inserted sidewise into said slots and into the turned inner ends of the slotsfin said inner telescoping member,

whereby said member inserted sidewise is clamped betwecnthe edges ,of the slots of saidtelescoping members! i 6; In a deviceof the character shown, a supporting member, a sleeve havingoneend seated in the side of said supporting member and having its opposite end slotted on opposite sides from its end inwardl to provide two opposed open slots, a tel ascoping member telescoping with saidsleeve and having its outer end slotted from the'end ill) inwardly, said slot turning'to an angle at the inner end, saidslot being adapted to register with the slot in said sleeve,.wliereby a member can be moved sidewise into said open slots in said members, means for turning said inner member to turn the angular part of saidslot. around. said member when inserted sidewise therein, means on the opposite side'of said supporting member and connected therethrough and through saidsleewe for drawing-said inner member. into sa d sleeve and holdmgit, a springin said sleeve normally and yieldmgly pressing said inner member outwardly, whereby when released said inner member ,moves outwardly from said sleeve, and a member to be held inserted sidewise into said slots, substantially as described.
